ELOUILD DUPLESSIS, OF ST. HYACIN THE, CANADA, ASSIGNOR TO THE DUPLESSIS PEGGING AND SEWING MACHINE COMPANY, OF SAME PLACE.

PEGGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 651,415, dated June 12, 1900.

Application filed February 17, 1899. Serial No. 705,930. (No model.)

To all whom it may concern:

Be it known that I, ELoUILD DUPLESSIS, of the city of St. I'Iyacinthe, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Pegging Machines; and I do hereby declare that the following isa full, clear, and exact description of the same.

My invention although applicable to almost any type of pegging-machine is particularly applicable to a machine of the type set forth in Letters Patent of the United States granted under No. 594,466 on November 13, 1897, and No. 616,699 on December 27, 1898, and Letters Patent of the Dominion of Canada granted under No. 58,455 on December 20, 1897, and No. 62,443 on January 25, 1899.

The object of the present invention is to greatly simplify and consequently reduce the cost of the production of pegging-machines generally; and to these ends the invention may be said, briefly, to consist in arranging in a particular manner a stationary cutter carried upon an annular stationary part of the nose of the horn or work-support, said annular part having a centripetally-extending arm formed on the interior thereof and carrying a vertically-adjustable screw to support a plate. This cutter is preferably held in place by an annular part adapted also to serve as a work-supporting portion, while the before-mentioned plate,which is free of the cutter and located on the side thereof, serves, in conjunction with said annular retaining part, to support the work, the last-mentioned part being preferably adjustable in order that it may be kept constantly on approximately the same pl .e as the cutter.

In a pegging-machine comprising a stationary horn or work-support a knife of only sufficient length to diagonally intersect the line oftravel of the driven pegs is necessary; but in a machine comprising a swinging horn the cutter should be curved concentrically of the arc in which the horn swings and be of sufficient length to at all times intersect the line of travel of the driven pegs. This latter embodiment of my invent-ion is hereinafter described, and illustrated in the drawings, in

removed; Fig. 5, a similar view with worksupporting portion removed; Fig. 6, a transverse vertical sectional view, taken on line 6 6, Fig. 2, of the nose of the horn with all the parts assembled; and Fig. 7 a similar view taken on line 7 7, Fig. 2. I

The nose of the hornlO is circular in plan view and has an externally-screW-threaded annular vertical project-ion 12 formed integrally therewith, while the interior opening of said annular projection extends downwardly completely through the nose of the horn, as at 13. A centrolineally-projecting arm 14 is formed on the interior of the rear portion of said annular projection 12 and with its inner free endlocated concentrically thereof and provided with a vertical screwthreaded boring 15, adapted to receive a screw 16, having its upper end flattened, to be presently further alluded to. The cutter is in the form of a ring 17, having its inner edge sharpened to a knife-edge, as at 18, and this cutter is held in place by a short sleeve 20, having its upper end of reduced interior diameter, as at 21, and the interior of its main body portion screw-threaded to take into the screw-threads upon the exterior of the annular projection 12. A Work-supporting plate 30 is supported upon the arm 14 through the screw 16 and is held in place by a retaining-screw 31, taking through the plate into said arm 14. This work-supporting plate has its inner end curved concentrically of the cutter and its outer end made to conform to the contour of the interior of the annular projection 12, while the space intermediate the arm 14 and the forward portion of said pr0 jection 12 (relatively to the direction of feed) is filled in by an upwardly-flared web 40.

Looking at Fig. 2, the feed will be in the direction indicated by dotted lines, and it is apparent that as the work is fed the protruded ends of the pegs will be caused to impinge upon the portion of the cutter that projects diagonally in a curved line across their path, thus severing such ends by an angular drawing action.

My object in making the cutter annular and securingitagainst displacement by the sleeve shown is to enable the cutting edge to be shifted around its axis, as the portion thereof most frequently used becomes dull, While by lowering or raising the screw 16 the worksupporting plate 30 can be set in a plane to either conform to that of the cutting edge, and thus sever the ends of the pegs flush with the work, or in a higher plane to cause the ends to besevered with a portion projecting slightly through the work, as is sometimes required, the flared Web preventing the cutaway portions jamming in the passage 13.

What I claim is as follows:

1. In a pegging-machine, a horn or worksnpport formed with an annular stationary part; a cutter consisting of a ring having its inner edge sharpened, and rigidly mounted upon said annular part and concentrically thereof and said annular part havingits perimeter screw-tln'eaded, a retaining-sleeve hav ing its upper edge diminished in interior diameter to bear upon said ring and having the interior of its lower portion scre\\'-threa(.led to take into the screw-threads of said annular part; a centripetally-extending arm formed on the interior of said annular part; a vertically-adjustable screw carried by the inner end ef'said arm; an upwardly-flared web connecting one side of said arm to the adjacent portion of said annular part; and a work-supporting plate secured to said arm and resting upon said vertically-adjustable screw, substantially as described and for the purpose set forth.

2. In a egging-machine, a horn or Worksupport formed With an annular stationary part, a cutter, mounted on said annular stationary part, a centripetally-extending arm formed on the interior of said annular part and an upwardly-flared web connecting one side of said arm to the adjacentportion of said annular part, substantially as and for the purpose set forth.

3. In a pegging-machine, a horn or worksupport formed with an annular stationary part,a cntter,mounted upon said annular stationary part, a centripetally-extending arm formed on the interior of said annular part, a vertically-adjustable screw carried by the inner end of said arm; and a work-supporting plate resting upon said screw and secured to said arm, substantially as and for the purpose set forth.

4; In a pegging-machine, a horn or worksupport formed with an annular stationary part,a cutter,mounted upon said annular stationary part, a centripetally-extendi11g arm on the interior of said annular part and an npwardlydiared web connecting one side of said arm to the adjacent portion of said annular part, a vertically-adjustable screw carried by the inner end of said arm; and a worksupporting plate resting upon said screw and secured to said arm, substantially as and for the purpose set forth.

In testimony whereof I have afiixed my signature in presence of two witnesses.
